[Dovecot] deliver to subfolder with dovecot's LDA
by Tom Bombadil 17 Mar '07

17 Mar '07

Hi all... How can deliver messages to a subfolder using the LDA? For example, I want a message to joe+spam(a)abc.com to be placed inside the 'spam' subfolder. Any hint is appreciated. Thanks ;)

[Dovecot] flock problems with index files and passwd-file
by Michal Soltys 17 Mar '07

17 Mar '07

While experimenting a bit, I found that for some reason, locking indexes with flock is problematic, but only if user is taken from passwd-file. The host system is openbsd 3.9, dovecot's configuration is added at the bottom. Authentication is from two places - first from mentioned passwd-file, then from passwd file using bsdauth (in this case, there're no problems with flock). So, if a user is i.e.: test@domain.tld:{plain}test:20000:10::/home/regular/test::userdb_mail=maildir:~/Maildir Then the mail client will timeout (thunderbird in this case), and dovecot will leave following info in the logs: Mar 15 11:13:38 rasengan dovecot: IMAP(test(a)domain.tld): Effective uid=20000, gid=10, home=/home/regular/test Mar 15 11:13:38 rasengan dovecot: IMAP(test(a)domain.tld): maildir: data=~/Maildir Mar 15 11:13:38 rasengan dovecot: IMAP(test(a)domain.tld): maildir: root=~/Maildir, index=~/Maildir, control=, inbox= Mar 15 11:15:38 rasengan dovecot: IMAP(test(a)domain.tld): Timeout while waiting for lock for transaction log file /home/regular/test/Maildir/dovecot.index.log Happens both if in maildir and mbox (userdb_mail=mbox:~/mail:INBOX=/home/regular/test/mbx) cases. Locking through dotlocks or fcntl works well in all situations (passwd-file or not).

[Dovecot] LOCKD errors
by Jay Chandler 16 Mar '07

16 Mar '07

Running the nightly from two days ago. The Dovecot log shows no errors, but I keep getting login errors for a few users. top shows: 71486 user1 1 96 0 4552K 2408K lockd 0 0:00 0.00% imap 11170 user2 1 96 0 4440K 2480K lockd 0 0:00 0.00% imap And a ps aux shows that these processes have been open for hours. If I move the mbox that contains their mail, the same error still shows up. The mboxes reside on our NetApp which is NFS mounted-- does anyone have any wisdom regarding this? As best I can tell this hasn't been a problem before the last few RCs, though I could be mistaken on this. -- Jay Chandler Network Administrator Chapman University

[Dovecot] wiki -> txt
by Timo Sirainen 16 Mar '07

16 Mar '07

I've been trying to fix MoinMoin's text_plain formatter to produce readable output. It's almost correct, except I don't understand why I can't get the LF-adding rules correct. Either there are too many LFs or too few. And whenever I change something, something else breaks.. It's getting pretty annoying. So if anyone else wants to try getting it fixed that'd be great. :) Attached the current version that I have. For testing you'll need your own MoinMoin installation. Then replace the included text_plain.py with the attached version. Then test it with for example: http://localhost/wiki/SomePage?action=format;mimetype=text/plain

[Dovecot] unable to connect to auth server

Upon rebooting our Dovecot server, I got these: Mar 16 09:49:16 peridot.tc.umn.edu dovecot: [ID 195972 local6.info] Dovecot v1.0.rc27 starting up Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 1 time Mar 16 09:49:18 myhost.mydomain dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 2 times Mar 16 09:49:18 myhost.mydomain dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 2 times Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain last message repeated 1 time Mar 16 09:49:18 myhost.mydomain dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 16 09:49:18 myhost.mydomain dovecot: imap-login: Can't connect to auth server at default: Connection refused However, everything does work okay.

[Dovecot] crypt missing (configure problem)
by Fabio Busatto 16 Mar '07

16 Mar '07

Hi, I need some feedback for the following problem I encountered compiling dovecot. It seems to be a wrong check in configure, that comes out in a fatal error (crypt symbol not found because the -lcrypt is omitted). With these configure parameters no crypt module is recognized (and so the need_crypt variable is still off), but at compile time gcc fails to create executables. I solve the issue forcing the need_crypt variable to on in configure, but maybe it can be solved clearly adding the right checks. Here is some info: Dovecot: tested on 1.0.rc17 and 1.0.rc27 OS: linux Configuration parameters: ./configure --without-passwd \ --without-passwd-file \ --without-shadow \ --without-pam \ --without-bsdauth \ --without-gssapi \ --without-sia \ --without-ldap \ --without-vpopmail \ --without-static-userdb \ --without-sql \ --without-pgsql \ --without-mysql \ --without-sqlite \ --without-deliver \ --without-sql-drivers \ --with-storages=maildir \ --disable-ipv6 Here there are the errors: Making all in auth make[3]: Entering directory `/usr/src/dovecot-1.0.rc27/src/auth' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -export-dynamic -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -export-dynamic -ldl gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o dovecot-auth auth.o auth-cache.o auth-client-connection.o auth-master-connection.o auth-master-listener.o auth-module.o auth-request.o auth-request-handler.o auth-stream.o auth-worker-client.o auth-worker-server.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-gssapi.o mech-rpa.o mech-apop.o passdb.o passdb-blocking.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-sia.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-blocking.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-prefetch.o userdb-static.o userdb-vpopmail.o userdb-sql.o -Wl,--export-dynamic libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -ldl libpassword.a(mycrypt.o)(.text+0x5): In function `mycrypt': /usr/src/dovecot-1.0.rc27/src/auth/mycrypt.c:20: undefined reference to `crypt' collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 Making all in util make[3]: Entering directory `/usr/src/dovecot-1.0.rc27/src/util' /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o dovecotpw dovecotpw.o ../auth/libpassword.a ../lib-ntlm/libntlm.a ../lib/liblib.a -export-dynamic -ldl gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o dovecotpw dovecotpw.o -Wl,--export-dynamic ../auth/libpassword.a ../lib-ntlm/libntlm.a ../lib/liblib.a -ldl ../auth/libpassword.a(mycrypt.o)(.text+0x5): In function `mycrypt': /usr/src/dovecot-1.0.rc27/src/auth/mycrypt.c:20: undefined reference to `crypt' collect2: ld returned 1 exit status make[3]: *** [dovecotpw] Error 1 Bye Fabio -- Fabio Busatto <fabio.busatto(a)sikurezza.org>

[Dovecot] BUG: Unexpected input from auth master:
by Justin McAleer 16 Mar '07

16 Mar '07

deliver logs the error in the subject whenever the userdb lookup fails. I had a query discrepancy between postfix and dovecot, so messages were accepted that shouldn't have been, but I figured deliver should probably handle that a bit more gracefully :)
